Why are commuters out for this man's blood?

A MAN who has been regularly travelling on a Sydney train has been getting away with outrageously inappropriate train behaviour for quite some time.

But now Kidspot reports that he's been publicly outed in a massive way and people are after his blood.

A woman had clearly had enough of this guy and his obnoxious ways, so she took to NSW Sydney Trains' Facebook page to tell the world about:

"Totally packed train each Thursday morning, when I catch the Blacktown to Hornsby train. Every morning we are greeted by this person, when you ask him, to move his bag & feet you get the finger," the woman says.

According to the Facebook poster, he flips people the middle finger when they ask him to move his feet.Facebook

At the very least she hopes his parents will find out and be bitterly disappointed with their boy - and at best - he gets slapped with a ban and fine for his antics.

"Please help this go viral maybe his parents will see, just how polite he is not. Maybe the rail cops should travel on morning commutes as well. He commutes to Pymble Station.," she says.

"Maybe a 12 month ban as well as a hefty fine might teach him a lesson."

The post seemed to resonate with commuters, with over 16,000 people sharing it and 8,800 people liking it.

Many of the comments were unprintable.

Some that were less aggressive include: "I'm sure they must have cameras on the train, and we teach our kids to not put their feet on chairs."

"Use his legs as a seat - sit on his knees."

"They should charge him for two tickets as he's using two seats or take a 6ft 7in bloke with you tomorrow."

"Spill hot coffee on him that way it'll look like he p*ssed himself when getting off the train. Just imagine how embarrassed he would when people would point & laugh him! Any takers ?! …"

It could come as an expensive lesson in manners for the man in question - the penalties for having your feet on the seat start at $100 and can climb all the way up to a whopping $1,100.
